INVENTOR A TTORNE Y8 citizen of the United States, residing PATENT oFFICE- LEOIPOLD SIMON, OF NEW YORK, N. Y.

' WIN DOW-SCREEN.

Application filed July 8,

To all whomit may concern: 7

Be it known that I, LEOPOLD SIMON, a at New York, in the county of NewYork and State of New York, have invented certain new and usefulImprovements in Window- Screens, of which the following is a full,clear, and exact description, such as will enable others skilled in theart to which it a-ppertains to make and use the same.

, This invention relates to screens, and with respect to certain morespecific features thereof, to adjustable and foldable light and airdeflectors for window, porch and other building purposes.

- One of the objects of the invention is to provide a device of theabove character which is capable of easy manipulation and is reliableand eflicient in operation.

A further object is to provide an improved screen adapted to controleffectively the passage of light or air therethrough, as desired.

A. further object is to provide a weather shield of the above characterwhich includes various features of structural and functional advantage.

Other objects and advantages will be in part obvious and in part notedhereinafter in connection with the following description of theaccompanying drawings, which illustrate a typical embodiment of theinvention.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the following claims.

In the drawings,

Figure 1 represents a screen applied to a window opening;

Fig. 2 is a vertical sectional view thereof; Fig. 3 is a perspectiveview of a part;

Fig. 4 is a sectional detail .of a screen strip and clamp; f

Fig. 5 is an isometric view of a rod support; and

Fig. 6 is a sectional view of a locking device.

Referring more particularly to the draw- I ings, there is indicated awindow casing having upright sides 1 and a transverse top 2, adjacentthe corners of which are secured a pair of supporting brackets 3. Aguidmg support 4, preferably in the form of a square rod or bar withround extremities,

is journaled to rotate freely in the brackets 3. A pair ofscreen-carrying devices are suspended from the rod 4 and are providedwith a plurality of flexibleor collapsible screens or screen strips 5extending therebetween. ably comprise transversely mounted angle membersor cross pieces 6 and 7 arranged at opposite ends of the rod 4 andhaving a pair of vertically disposed parallel links ,8

pivotally connected to their ends. Additional cross members 9 arepivotally connected between the links of each frame for attaching thescreensv and for insuring a parallel transverseand opposite simultaneousmovement thereof when the rod 4 is rotated. The angle member 7 ispreferably fixed to the bar 4 adjacent one side of the window casing 1,while the other angle member 6 is secured to a sleeve member or bracket11 having a square bearing aperture for the rod 4. The sleeve 11 is thusmounted for translatory movement on the support 4 toward and away fromthe other frame for collapsing or extending the flexible screenstherebetween. In order to render the sliding movement of the sleeve 11free, ball bearings 12 are seated inthe sleeve to ride on the support.

Locking means are preferablyprovided to either extended or retractedposition and thus maintain the screen strips taut or securely folded. Asillustrated, the locking means forthe first men? tioned purposecomprises a latch 13, pivoted to one end ofa bell crank lever 14, whichis in turn pivoted at 15 to the sleeve 11. A second and oppositelydisposed bell crank lever 14 is also provided to operate the latch 13for withdrawing the same from a -recess'18 in the left end of shaft, itsposition for holding the screen folded. A coil spring 16 located in arecess 16' in an offset lug of one bell crank lever works against aplunger 17 in said recess and bears on the sleeve Patented Aug. 2,1921.-

These devices or frames prefer-' 11 to urge the latch 13 to lockingposition, I

that is, toward one of two recesses 18 provided in the support 4adjacent its ends. An operating cord 19 is secured to the lever 14 at 20and runs in a pulley 21, whereby the erablyadjacent ever, being attachedto the free end of the bell crank lever 14 and runnln'g over a pu 1' ley23, so that, on manipulation of the said cord, the latch 13 is withdrawnfrom looking position and the translatable frame then moved.

A foldin longitudina ly device or brace 24 is provided their lower endsor other the support 4, for rigidly spacing the frames when separated.In practice, this brace comprises a loosely articulated member, as twoarms pivoted at their ends to cross channel irons connecting pointremote from 1 the paral-lel' linlfsbf the screen frames and b extendingdown through apertures provided therefor in the screen strips, the samebeing knotted below a pivotal eye 29 on the brace adjacent the elbowthereof. A suitable pendent weight 30 is carried b the cord 27 fornormally straightening t e latter. The offset forked arm of the slidingsleeve or bracket 11, above mentioned, is provided with a roller 31which travels in a path to intercept the take-up cord 27 so that, as thetranslatable frame is pulled to the left, after the brace is manuallybroken, theroller 31 engages the cord and carries thesame there with tofold the brace and screen strips upwardly between the side frames.

There are also the sides of the window casing having studs or pivotmembers 33 which take into central openings in certain of the crossmembers 9 of the frames and afford a rigid axis in addition to thesupport 4 about which the screen strips may be rotatably adjusted bysuitable means, such as a handle 34. To

' prevent displacement of the screen when the same is operated to foldedposition, a guide wire or rod 35 is provided at the lower end of thewindow and a pivoted central e e 36 on the lowest cross iron 9 serves tohoo the translatable screen thereto. The rod 35 thus holds the screenagainst swinging when extended or collapsed.

, In certain installations of the device, particularly with a screen ofrelatively great length, e. 9., more than six feet, it is desirable toprovide an intermediate supporting means, brace or carrier for the rodor bar 4 to prevent the same from sagging.

For this purpose, a bracket 37 is secured to the top of the windowcasing 2, and is provided with a depending shaft 38 which has journaledthereon a plurality, in the present of. horizontally disposed andequidistantly spaced arms or levers 39, 40,

between the frames 8, 8, pref-- provided brackets 32 on' 41 and 42.These arms are curved downward slightly and one of the same is normallyturned at right angles to the rod 4 to engage the lower surface thereofand support the same. As will be apparent, this arm extends in the pathof movement of the translatable screen frame, but as said arms are freeto rotate, the same will be turned through 90 by the right frame link 8as the latter travels to the left. Accordingly, the adjacent arm 39 willmove under and suport the rod 4 as the arm 42 leaves the same.

imilarly, reverse movement of the translatable frame, when extending thescreen, rotates the arms in an opposite direction, thus allowing thesleeve 11 to travel to the right and returning the arm 42 beneath therod 4. The bracket 37 is illustrated as provided with four arms sincethe screen is preferably divided into sections, when the same is relatively long, and in such instances four or more screen frames andsliding sleeves may successively pass and rotate'the arms 39, 42.

As illustrated in Figs. 2 and 3, the pivotally movable screen strips 5are superposed in parallel lanes and each comprises a flat longitudinabody portion 5 and longitudinal or axially disposed edge portions 5 and5 reversely inclined with respect to the body portion and transverselyof the axes of rotation. The screens are. mounted substantiallyequidistantly apart with axes in vertical alinement so that, as the sameare turned to approach an approximately vertical plane, the down-turnededge 5 of each effected so that light and air may be subi stantiallyexcluded from passage therethrough. Furthermore, the contour of thescreen units serves to materially prevent the entrance of rain or snowthrough the screen, even when the same are adjusted to admit a freecurrent of air.

In order that the screen units may be readily assembled or withdrawnfrom the other parts of the device when desired, end members, or clamps43 are provided therefor, consisting of flexible metal strips reflexedover the ends of the screen strips and then doubled to provide curved orexteriorly V-shaped members laterally insertible in the holders 9, whichalso constitute cross members for the links 8 and are bent to providelongitudinally extending transversely curved open channels 9 having awall or web 9" lying within the channel and projecting partwaythereacross to lie in the recess, or concavity, in the 'U-shaped member.The screen clamps may thus be readily telescoped laterally to nestwithin the holders, the clamps bein preferably longer than the holders,so that the ends of the former ex- 2. After assembly these projectingends are inclined or offset, as indicated, for the purpose of incliningthe edges of the screen member 5, as above set forth, and also forlocking the screen members against unintentional displacement.

While the operation of the device will be largely obviousfrom theforegoing description of thestructure, the same may be briefly set forthas follows: Assuming the screen to be in extended operative position, asillustrated in Fig. 1, the same may be folded or collapsed by manualrelease of the brace lock 26 and operation of the cord 22. The latterserves to automatically release the sleeve latch 13 and thereafter slidethe sleeve 11 and the right frame members to the left,

thereby collapsing the screens.' When the bracket 11 reachesmid-position on the support 4, the roller 31 picks up the brace cord 27and the latter, with the brace 24, takes up the slack in the screenstrips thus successively looping the strips and renders the whole devicecompact and firm when folded. Thereafter, manipulation of the oppositecord 19 releases latch 13 and moves the translatable frame to the right.whereupon the sleeve 11 will be locked in extended position and thebrace simultaneously stralghtened to rigidly longitudinally space thelower ends of the links 8, In the operation of extending the screen, theright frame will fit over the pivotal stud- 33 provided onthe rightwindow casing. It will be understood that the arms 39, 40, 41, and. 42operate in the manner above described to support the rod 4 and therebyprevent sagging or bendto provideone or more metal stripss44 securedlongitudinally to certain of the links 8.. These strips serve to closeany gap between the sides of the screen and the-window frame, and alsoto reinforce the links. Furthermore, when a plurality of the screens areprovided to operate in opposite directions on a single su port 4, themetal strips 44 overlap when t e sereens are extended and therebyprevent any objectionable openings between the screens when closed.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention couldbe madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not me limiting sense.

It is also to be understood that the langua e used in the followingclaims in ten ed to cover all of the generic and specific features of.the invention herein described, and all statements of the scope of thein vention which, as a matter of language, mi ht be said to falltherebetween.
